FILTER.

Specification of Letters Patent.A i Patented. April 27, 1909.

To all whom it mayconcern: i .i

Be it known that l, SAMUEL B. Gori, a citizen of the United States, residing at Cainden, in the county vof Camden, State of Newl Jersey, have invented a new and useful Filter, of which the following is a specification. n

My invention consists oli' an improvement in a filter, embodying'novel means for receiving the supply ofwater and distributing .it to a Jfilter bed, means for directing the i'iltered water from said. bed toa reservoir, and

derstood that the invention is not limitedto' the specilic arrangement and organization shown and described. fk

Figure l represents a vertical section .of a filter embodying the invention. Fig.2 .rep-V resents a horizontal section thereof. Fig. 3 represents a vertical section of a portion at a right angle to the section shown `in Fig. 1. Fig. l represents a vertical section ofthe stand-pipe and connectedV parts employed, on an enlarged scale." Fig. 5 represents a vertical section of one ot' the distributing` pi es and guard therefor employed, on an e arged scale. i i .n

Similar letters of reference indicate corresponding parts in the gures. y l

Referring to th vdrawingsz--A designates the casing of the lilter,` and B designates a tower, which constitutes the primary receiving tank, the same, in the present instance, being centrally supported in said casing in any sitable manner, and having a supply i e i Y f p Iltadiating from the lower portion ofsaid tower and in communication therewith are the perforatedperforated guar In the up er portion of thecasing is the trough F, w ose sides G and bottom H are pipes Q, overwhich are the s D, which also radiate from Ysaid tower, but are not' in-communication plate. J, and below the latter-is the inclined floor forming the -chamber K, said trough, sides, bottom and floor being suitably secured .to the wall of the casing A and tower B, they being surrounded by liltering substance or material E, as most plainly shown in Fig. 3.

Surroundingthe casing A is the reservoir L, whilel` is a chamber in communication withthe said reservoir by means of the port lvlfinthe wall of the casing at the outlet end ol' said chamber. ln the .reservoir is the stand-pipe N, which Ais in communication with thesarne by theV branch l), the latter raving a cock Q for turningon and cuttingoff purposes. lWithin the pipe N is a vertical; division R, at the top' of which is a per for-ated plate S, which is secured to the wall oli' said pipe N and sustains said division. Connected with the pipe N is the discharge lpipe T, which is provided with a cock U for evident purposes.

Within the tower B near the lower portion thereof is the valve V, which has gudgeons V mounted on the wall of said tower, it having a weight V2 thereon for closing purposes, and the towerv being provided with a stop-plate V 3 for holding said valve in closed position. ln order to raise the said valve, a

chain or other connection W is employedV the same passing Jfrom said valve upwardly through the tower, and passing out ol' the same is guided on the pulley W, which isv mounted on the tower, as 'plainlyshown-in Fig. 1.

In order to createa pressureof air on the water in the tower, there connected with the top of the tower the pipe X, which leads from a suitable source'of pressure and opens into the tower. l

In order to exhaust air from thestandpipe N,.there is connected with the top of `the sanie the pipe Y. v

The operation is asy followszfWater is admitted by the supply-pipe B into the tower B, .the valve V being opened, so that the tower is practically lilled. The water is fthen distributed from the tower into the pipes. C, from which it escapes upwardly therefrom and through the guards D to the ltering material .or lter-beds E, it being then subjected to the action of the latter, and so is filtered, in which condition, it

-reaches theperforated sides of the trough perforated.' vBelow said bottom isfa'strainer lll) F and flowing through the same enters said trough and escapes therefrom, and passing through the strainer J, reaches the chamber K, discharges therefrom into the reservoir L, thus supplying the latter with the filtered water, which is directed into the pipe N, and from thence through the pipe 'l to the place of service. Should itV be desired to subject the water to pressure, so as to direct it forcibly through the filtering-beds, this is accomplished by opening the valve of' the pipe Should it be desired to exhaust the air from the stand-pipe N, the valve of the pipe Y is opened.

The valve V may be opened to an extent that it may be desired .to allow the escape of' water from the tower B to the distributing pipes C, and said valve may be. couipletely closed to prevent the escape of water and thereby save the volume of' the saaie in the tower above said valve, when the valve of' the supply pipe B is closed. Then said valve V is opened and the water in the tower above the latter falls forcibly on the deposits or impurities in the lower portion of the tower and washes the saine through the filter, after which the fresh or unfiltered water is again turned on and the tower is refilled, and the filtration continues as before.

I have described my invention as applied to the filtration of water, but as is evident, it is serviceable for similar purpose for other fluids.

To compensate for any back pressure in the pipe T, and consequently in the stand pipe, the plate S in the latter is deflected angularly upwardly,where it joins the division R, thus providing a pocket S at the inner angle of' the plate and division, which in a measure vchecks said back pressure, thus preventing objectionable results therefrom.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:-

1. In a filter, a tank, a perforated pipe, a casing containing said tank and pipe, said pipe leading from said tank, a supply pipe for said tank, a filter-bed in said casiiw, a conductor for filtered fluid from said bed, a reservoir containing said tank, pipe and casing and with which said conductor is in communication, and a stand pipe in said reservoir outside said casing.

2. In a filter, a lter-bed, a conductor for filtered fluid in said bed, a chamber leading frein said conductor, a reservoir surrounding said filter bed and in communication with said chamber and a stand pipe in said rcservoir outside of said chamber.

3. In a filter, a tank, a pipe connected therewith, a casing containing said tank and pipe, a filter-bed in said easing, the saine being adapted to receive unfiltered fluid from said pipe, a reservoir around said casing, .means in the casing adapted to direct filtered. fluid from said bed to said reservoir, anda stand-pipe in communication with said reservoir.

4. ln a filter, a tank, means for supplying the saine with unfiltered fluid, a casing containing said tank, ineans for directing the fiuid from said tank, a filter-hed in said casing, means for discharging the filtered fluid from said bed, and means for creating pressure on the unfiltered fluid contained in said tank.

5. In a filter, a tank for unfiltered fluid, casing containing the same and eonnnunicating therewith, a filter-bed in said casing, a reservoir for filtered fluid, means for directing the filtered fluid from said bed to Said reservoir, a stand-pipe connected with said reservoir, and means for exhausting air from said pipe.
